This sentence came from the poem "Climbing the Stork Tower" by the Tang Dynasty poet Wang Zhihuan. The whole sentence is: "The sun is against the mountains, the Yellow River flows into the sea." I want to see a thousand miles and climb another level. I don't know where the face is going, but the peach blossoms are still smiling in the spring breeze." It meant that the face of a person did not know where to go, and the peach blossoms were still smiling in the spring breeze. It expressed the poet's love for natural beauty and his understanding of the short and precious life.
